LAUSANNE, Switzerland — With the opening ceremony in Rio de Janeiro just over two months away, Olympic leaders have plenty of troubling issues to deal with this week.
The Zika virus, unfinished venues and political chaos in Brazil. A flood of positive drug tests from the past two Summer Games. Fresh accusations of state-sponsored doping in Russia. Vote-buying allegations involving Tokyo's winning 2020 bid.
All these challenges and more will be on the table when the International Olympic Committee executive board holds a three-day meeting starting Wednesday in Lausanne. It's the last meeting before the IOC gathers in Rio on the eve of South America's first Olympics.
The policy-making board will also name the team of Olympic refugee athletes for Rio, consider the proposed five additional sports for the Tokyo Games, review the bidding for the 2024 Olympics and nominate several new IOC members.
"I can't recall an executive board meeting with so many issues on the agenda," IOC vice president Craig Reedie told The Associated Press. "There is a whole range of difficult issues facing the Olympic movement, led by Rio."
A look at what's keeping the IOC busy:
RIO: READY OR NOT?
Rio organizing committee president Carlos Nuzman will give his latest update Thursday on preparations for the games, which open on Aug. 5. The buildup has been dogged by political, economic and public health crises.
Last week, a group of 150 scientists suggested the Olympics should be postponed or moved because of the outbreak of Zika, which has been linked to severe birth defects. But the World Health Organization said there was "no public health justification" for scrapping the games, and Olympic officials have repeatedly said they will go ahead.
Some leading athletes have expressed concerns about going to Rio. Spanish NBA star Pau Gasol said Monday he may skip the games because of the Zika threat and that other Spanish athletes were also considering staying away.
Meanwhile, Dilma Rousseff has been suspended as Brazil's president pending a Senate impeachment trial, with Michel Temer taking over as acting president. A final vote on removing Rousseff could come on Aug. 2 — three days before the opening of the games.
Brazil is dealing with its worst economic recession since the 1930s, leading to the slashing of Olympic budgets.
Some sports venues are behind schedule. UCI President Brian Cookson said he remains "very, very concerned" about delays to the velodrome, and the city said Monday it is changing contractors to take over the construction. ITF President David Haggerty said "an awful lot of work" is needed to get the tennis venue ready for the games.
Water pollution remains a concern for Olympic sailing, rowing and open water swimming events. Crime is a worry: Three Spanish sailors were recently robbed at gunpoint in broad daylight while training in Rio.
DOPING, DOPING, DOPING
Reedie, president of the World Anti-Doping Agency, will deliver a report that will include an update on the agency's independent probe into allegations by Moscow's former drug-testing lab director, Grigory Rodchenkov, that he operated a state-backed doping scheme for Russian athletes that involved switching tainted urine samples for clean ones during the 2014 Winter Games in Sochi.
Russia's track and field athletes remain suspended from global competition, with the IAAF to decide on June 17 whether to keep or lift the ban for the Rio Games.
The IOC has recorded 55 positive results in retests of Olympic doping samples — 32 from the 2008 Beijing Games and 23 from the 2012 London Games. The tests were designed to catch cheats who might compete in Rio. More positives are expected.
The Russian Olympic Committee said 14 of its athletes from Beijing and eight from London tested positive. The IOC is retesting the "B'' samples before announcing sanctions and medal reallocations.
The IOC board will examine the proposed addition of baseball-softball, surfing, skateboarding, karate and sports climbing for the Tokyo Games. The sports, which would add 18 events and 474 athletes, were recommended for inclusion last year by Tokyo organizers.
While some officials have expressed concern over whether skateboarding has a unified governing body, the board is likely to recommend the five sports for inclusion as a package, which will go to a vote of the full IOC at its session in Rio before the games.
TROUBLE IN TOKYO
After controversies over the main stadium, venue changes and the Olympic emblem, Japanese organizers are now embroiled in a corruption probe.
Leaders of the Tokyo bid acknowledged making payments, before and after the 2013 vote, totaling about $2 million to a Singapore company linked to Papa Massata Diack, son of former IAAF President Lamine Diack. The younger Diack is the subject of an Interpol wanted notice. Lamine Diack, a former IOC member, has been accused by French prosecutors of taking more than $1 million in bribes to cover up Russian doping cases.
Japanese Olympic Committee president Tsunekazu Takeda, who headed Tokyo's bid, said the payments were for legitimate consultancy work. The committee has opened an investigation; the IOC says it remains a civil party to the French probe.
On Friday, Bach will announce some feel-good news — the names of the refugee athletes who will compete as a team under the Olympic flag in Rio. A total of 43 refugees were originally considered for the team, including a teenage female swimmer from Syria, long-distance runners from central and western Africa, and judo and taekwondo competitors from Congo, Iran and Iraq.
While Bach initially said he expected the final list to comprise between five and 10 athletes, officials say the number could reach 12 to 15.
